In order to transform into high-end products, Xiaomi stripped Hongmi of its brand identity. After independence, red rice was renamed " Redmi ", the" cost-effective "concept of the original Xiaomi digital series will be continued by Redmi. Redmi named its flagship mobile phone for the high-end market " Redmi K "Series, the first generation products are" Redmi K20 "," Redmi K20 Pro "and" Redmi K20 Pro Exclusive Edition ".

Because at first, "there was no money Buy millet ", but now" No money to buy "Xiaomi", I thought I could no longer afford the transformed Xiaomi mobile phone, until the initial price of "2499 yuan" Redmi K20 Pro , let me rekindle the hope of purchasing millet products. Therefore, I bought this Redmi K20 Pro in September 2019, and replaced the one that was more difficult to use Sony XZ1

user's experience

In this age when everyone is learning from Apple, we have an extremely advanced 3.5mm headphone connector , which is definitely a selling point worth showing off. Thank God for giving me the headphone jack, so that I don't need an additional adapter. I think Apple cut the headphone hole to promote its own Bluetooth headset. What's the reason why Android cut the headphone hole? Blind learning is really undesirable.

However, it is a pity that the Redmi K20 Pro does not have infrared. After all, the standard NFC and infrared of Xiaomi's mobile phones are almost engraved in DNA, and these two functions have always been Xiaomi's promotional selling points. It may be due to the pop-up camera and cost constraints that infrared has been cut off. Well, I'm no longer a bad kid who likes to secretly use my mobile phone to adjust other people's air conditioners, so infrared is not a problem.

Speaking of cameras, for people like me who don't take selfies except for face authentication, I really don't want to dig a hole or put a bangs on the screen to place a front camera. Therefore, the "pop-up" design of the Redmi K20 Pro has really won my heart. Ah! Look at the complete forehead and the flat screen. This is the full screen mobile phone I expect.

Although the post three shots are flagship level, the actual experience is just ordinary. Redmi's optimization of this shot is not very good. No matter taking photos or videos, it cannot achieve the effect of publicity photos. I can only comfort myself that what kind of bike does a mobile phone at this price need? Don't think about competing with Huawei for photos.

However, just looking at the 6.39 inch screen, it is impossible to operate with one hand easily. What's more, Gunda 191g Weight of. The XZ1, a Sony mobile phone with the title of "Suo Ban Jin", is only 156g. During my daily use, my mobile phone will be thrown out if I am not careful, so wearing a suitable phone case is the basic protection work that must be done.

As for other experiences, there is nothing to say. The 4000mAh battery can be used for a day at a mild level, and the severe level depends on the use scenario; AMOLED's rest screen display is also very practical, but I will still miss the LCD display effect. LCD will never be a slave! Fever is not as serious as Xiaomi 5; In terms of speakers, because there is only one speaker, it can only be played out. I don't play it out. I wear headphones.

Brush machine

Redmi K20 Pro's brushing steps and Xiaomi 6 It is basically the same. When a new phone arrives, first bind the account, unlock it, swipe TWRP, and then swipe the phone.

The general steps of brushing the machine are as follows:

  2. After unlocking, go to the TWRP official website to download the dedicated TWRP for Redmi K20 Pro. Please refer to my writing for the manual flushing method XZ1 is brushed into TWRP Methods;
  3. Then, it can be uploaded into the system, either as a native or as an official. Recommended by Ku'an Starry Future Modified MIUI system produced.

The unlocking step is skipped. Please refer to the " Xiaomi 6 brush pointing north ".

Brush in ROM

Before the machine is flushed, the most important thing to do is to back up the data. Please also refer to " Xiaomi 6 brush pointing north ".

In addition, please prepare the cleaning package and put it in the folder you remember, or directly in the root directory.

Then, by default, you have just swiped TWRP, and will automatically enter the TWRP interface with the help of the one click tool. To access TWRP manually, press and hold the "Power On" and "Volume+" keys.

For the first time, you need to clear the phone data. Click "Clear" to enter. (See Figure 2 above). Select "Slide to Confirm Factory Recovery" (double clear) or "Format Data Partition" (triple clear) as appropriate. Generally, double clearing is enough, but three clearing may be required to downgrade the Android system.

After the above operations are completed, click "Click" to enter into the machine cleaning package selection page. Select the brush package you have prepared, slide the slider to confirm the brush in (as shown in Figure 2 above), and wait until the brush is completed.


At first, I was keen to experience the native system, but now I don't want to bother with these things. First, it is troublesome to backup and transfer data; Second, the native system is not functional enough, and the MIUI system is getting better and better; Third, there is no joy of enjoying the process of machine brushing at the beginning.

Well, after all, it's laziness.
